开房间

verb

to rent a hotel/guest room; to check into a hotel room

A dialectal expression common in Southern China, especially in Wu dialect areas like Shanghai and Zhejiang. It specifically refers to the act of renting a room in a hotel, inn, or guesthouse. Note: In modern, broader Mandarin usage, especially online or in casual speech, this phrase can carry an additional, more suggestive connotation of renting a room for a romantic/sexual encounter. However, the primary dictionary definition and the original dialectal meaning is the neutral act of renting accommodation.
